Solve for x.<br><br> 8x^2-3=2

Mazyrski [523]

$(2^3x^2 - 3) - 2 = 0 \\ \\ Factoring: \ 8x^2-5 \\ \\ 8x^2 - 5 = 0 \\ \\ Add \ 5 \ to \ both \ sides \ of \ the \ equation : \\ \\ 
 8x^2 = 5 \\ \\ Divide \ both \ sides \ of \ the \ equation \ by \ 8: \\ \\ 
 x^2 = \frac{5}{8} = 0.625 \\ \\ \boxed{ x =\pm \sqrt 5/8}$

A Pharmacist whishes to mix a solution that is 6% Minoxidil. She has on hand 100 ml of 4% solution and wishes to add some 8% sol

Kaylis [27]

Answer:

She would need 100 ml of the 8% solution

Step-by-step explanation:

You can always answer these questions using a proportion. The numerator will represent the amount of Minoxidil, and the denominator will represent the total amount of solution

She already ha 100 ml of a 4% solution. That means that she has 4 ml of Minoxidil already

$\frac{4 + 0.08(S)}{100 + S} =\frac{6}{100}$
